The worst about HD failure is it's instant, often with no warning.

I'm into another round of repairing lightning damage here. Got hit the
day before leaving for Canada. This got our Sat TV, two computers and a
printer. And a dozen surge suppressers here and there in the system.
I've yet to loose a HD due to lightning, it's usually just I/O damage.
Inconvenient, but insurance always covers.

I too find the number of optical disks quite manageable. Particularly in
photos I occasionally go back through and cull which cuts the space used.

I'm holding off on DVD, want to see it better stabilized as to format
and a lot more common in this kind of use. See more track record.
